The most 'derided' variant of the imperial dragons, wyverns are predominantly based upon the wuivre, but trades the two forelegs for an even larger set of wings, and are notable for their lighter bone structure and resultant frailty, but this allows them to fly without the magical aids required by other imperial dragons.

Wyverns are known for their natural capability to fly without the aid of magical abilities, and this grants them a very unique benefit within the draconic world; they're fast, agile, graceful, and extremely capable ambush and hit-and-run combatants. They're not as magically gifted as the lung or the wyrms, nor are they as physically brutish as the wuivre, yet they are capable of being just as deadly with their extreme precision and speed.
